Eye Exam Explained

At Vision 2 Opticians our opticians or optometrists (as they are sometimes known as) will assess the health of your eyes and your prescription during the eye examination.

What happens at an eye examination?

Initial Discussion
Firstly the optometrist will ask you a few questions like do you feel you have trouble with your eyes? Are you having headaches? How old are your current spectacles or contact lenses? Is there any family history of eye disease?

Vision Check
Then they will check your current vision with or without your existing spectacles.

Retinoscopy
This gives the optician an estimation of your prescription without you having to say anything. They carry out this exam by shining a light into your eyes.

Refraction
This is the part of the test that will be most familiar to you. Reading the chart, the optician will ask you a few questions to establish the best prescription for you. Always remember that there are no wrong or right answers, just tell the optician what you are seeing and together you will achieve the best spectacles for you. Normally your distance vision will be checked first and then your near vision will be assessed. Another test which ensures that your eyes are working together, can be carried out at this stage. This is called Muscle Balancing.

Ophthalmoscopy
This part of the eye examination is most important. The optician will shine a bright light into your eyes and then they can check the health of the back of
your eyes which shows the blood vessels running freely so therefore various
diseases can be assessed and monitored.

Tonometry
This Instrument takes the pressures in your eye. It is very important in assessing the eye in relation to Glaucoma. (Click here for explanation of glaucoma) It gives a small puff of air into your eye and it doesn't hurt, but may make you jump.

Slit Lamp Examination
This instrument has many uses. Mainly in the assessment of the eyes for contact lenses. You place your chin into the chinrest and the optician uses a bright light to see your eyes in 3D. It is also used to see deep into the interior of the eye with some special attachments.

Keratometry
This measures the curvature of the front of the eye, also used in assessment of the eye for contact lenses and to monitor any curvature changes due to disease or over wear of contact lenses.

Visual Field Analyser
This assesses your peripheral vision. You look into a machine and focus centrally on a target and it shows you many lights at various intensities. It is mainly used to asses nerve damage in glaucoma but would have other roles in modern optometry. It is now mandatory for Driving Licences.

What happens after your eye examination!

Your optician will explain their findings to you and recommend whether you need spectacles or not. Our optical assistant may help you choose frames that best suit your personality and prescription. Then your lens options will be discussed and you can decide what best suits your needs.
